Abstract
A switch of a connecting circuit is connected between a signal line branched from an input terminal for a pilot signal in a charging inlet and a ground line connected to a vehicle earth, and is turned on/off in response to a control signal from a CPU. The CPU causes the switch to be turned on when a connector is not connected to the charging inlet, and detects a break in a control pilot line based on whether or not a change in the potential of the pilot signal occurs at that time.
